1. The pressure in an automobile tire depends on the temperature of the air in the tire air temperature is at 545.67 Rankine, the pressure gauge reads 245 kPa. If the vo tire is 0.025 m', determine the pressure rise (in lbf/in units) in the tire w temperature in the tire rises to 70 °C. Also determine the amount of air that must to restore pressure to its original value at this temperature. Assume the atmosphe to be 101.325 kPa.

Transcribed Image Text:1. The pressure in an automobile tire depends on the temperature of the air in the tire. When the
air temperature is at 545.67 Rankine, the pressure gauge reads 245 kPa. If the volume of the
tire is 0.025 m', determine the pressure rise (in lbf/in units) in the tire when the air
temperature in the tire rises to 70 °C. Also determine the amount of air that must be bled off
to restore pressure to its original value at this temperature. Assume the atmospheric pressure
to be 101.325 kPa.
